public class InstantDemo {
   public static void main(String[] args) {

      Instant instant = Instant.parse("2017-02-03T10:37:30.00Z");
      System.out.println("Instant #1: " + instant);  

      Instant instant1 = Instant.parse("2017-03-03T10:37:30.00Z");

      int result = instant.compareTo(instant1);
